UKRI has awarded contracts to run elements of the next national supercomputer, ARCHER2, which will represent a significant step forward in capability for the UK’s science community. ARCHER2 is provided by UKRI, EPCC, Cray (an HPE company) and the University of Edinburgh. “ARCHER2 will be a Cray Shasta system with an estimated peak performance of 28 PFLOP/s. The machine will have 5,848 compute nodes, each with dual AMD EPYC Zen2 (Rome) 64 core CPUs at 2.2GHz, giving 748,544 cores in total and 1.57 PBytes of total system memory.”
